Abstract
The invention discloses a hard alloy cutter which consists of a cutting part and a clamping part, wherein the cutting part comprises end face edges on the end face and spiral blades which axially and spirally extend and positioned on the outer surface of the cutting part, and chip spaces are formed among the spiral blades; the clamping part comprises cooling grooves, a big clamping rod, a small clamping rod and a catch; the cooling grooves penetrate through the big and small clamping rods, and the end parts of the cooling grooves are communicated with the chip spaces. During milling, a cooling medium is poured into the cooling grooves, so that the contact face of the cutter and a workpiece is cooled, and thus the temperature is effectively reduced. The big and small clamping rods are suitable for clamping milling machines of different models. According to the hard alloy cutter disclosed by the invention, the influence of heat generated by friction of the cutter and the workpiece on the workpiece and the cutter is reduced, the service life of the cutter is prolonged, and the processing quality of the workpiece is ensured.
Description
Technical field
The present invention relates to a kind of hard alloy cutter, belong to Machining Technology field.
Background technology
In mechanical processing process, need to use milling cutter to mill out end face, inclined-plane, groove or step surface to different workpiece, existing milling cutter is when carrying out milling to workpiece, and the metal fillings milled out is not easy to discharge, easily get lodged in the annex of cutter and machined surface, affect machining accuracy and the quality of workpiece.And the friction between cutter and workpiece can produce higher temperature, under long high temperature, certain impact can be produced on cutter and workpiece, the problems such as namely cutter easily damages, Workpiece Machining Accuracy reduction.
Summary of the invention
The object of the present invention is to provide a kind of hard alloy cutter, in milling process, can cool cutter and processing work.
For achieving the above object, the technical solution used in the present invention is as follows:
Hard alloy cutter, is made up of cutting portion and clamping part, and wherein, described cutting portion comprises the helical edges of the end face sword being positioned at end face and the axial screw being positioned at cutting portion outer surface extension, forms chip area between described helical edges; Described clamping part comprises cooling bath, large supporting rod, little supporting rod and catch, described catch is sleeved on cutting portion, described large supporting rod is fixed on the bottom of cutting portion, be little supporting rod below large supporting rod, described cooling bath runs through large supporting rod and little supporting rod, and the end of described cooling bath communicates with chip area.
Aforesaid multiple end face sword is evenly distributed on cutter end face, and each end face sword correspondence connects a helical edges.
Aforesaid end face sword is 2-5.
When the aforesaid diameter when cutting portion is 3-5mm, the length of helical edges is 5-6mm.
When the aforesaid diameter when cutting portion is 8-10mm, the length of helical edges is 11-12mm.
The surface of aforesaid cutting portion is provided with the aluminium nitride chromium overlay film that a layer thickness is 0.5-0.7mm.
The present invention is in milling process, cooling medium enters chip area by cooling bath, cools blade and workpiece, and the heat produced when reducing cutter and friction of workpiece is on the impact of workpiece and cutter, extend cutting-tool's used life, ensure that the crudy of workpiece; Be provided with large supporting rod and little supporting rod in addition, be applicable to the clamping of the milling machine of different model, the scope of application is wider.
Accompanying drawing explanation
Fig. 1 is the structural representation of hard alloy cutter of the present invention.
Detailed description of the invention
Now with detailed description of the invention, the present invention is described in further detail by reference to the accompanying drawings.
As shown in Figure 1, hard alloy cutter of the present invention is made up of cutting portion and clamping part, and wherein, cutting portion comprises the helical edges 3 of the end face sword 2 being positioned at end face and the axial screw extension being positioned at cutting portion outer surface, forms chip area 1 between helical edges 3.Clamping part comprises cooling bath 4, large supporting rod 6, little supporting rod 5 and catch 7, and wherein, catch 7 is sleeved on cutting portion, and during milling, according to the degree of depth of spiral vertical milling, fixing catch 7 in place, improves the precision of milling.Large supporting rod 6 is fixed on the bottom of cutting portion, is little supporting rod, is suitable for the clamping of the milling machine of different model below large supporting rod 6.Cooling bath 4 runs through large supporting rod 6 and little supporting rod 5, and the end of cooling bath 4 communicates with chip area 1, i.e. the corresponding cooling bath of each chip area.In process, cooling medium is poured in cooling bath, can cool the contact surface of cutter and workpiece, effectively reduce temperature.
Preferably, multiple end face sword is evenly distributed on cutter end face, and each end face sword correspondence connects a helical edges.End face sword can be 2-5.
The length of helical edges and the diameter of cutting portion are associated, and preferably, when the diameter of cutting portion is 3-5mm, the length of helical edges is that 5-6mm is optimum.When the diameter of cutting portion is 8-10mm, the length of helical edges is that 11-12mm is optimum.
Preferably, the surface of cutting portion of the present invention is provided with the aluminium nitride chromium overlay film that a layer thickness is 0.5-0.7mm, and this aluminium nitride chromium overlay film can improve cutting ability effectively, and stable cutting, cutting force can not be affected simultaneously.
